What else we do in Goathurst Common
For landlords and businesses
Landlords and agents in Goathurst Common can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Record problems with dated pictures
- Act quickly if a seal starts to leak
- Don’t seal over failed sealant yourself
- Ventilate bathrooms well, especially in the first year
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
What the job involves on each surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in.
Goathurst Common questions
Will you come out to Goathurst Common?
Yes, Goathurst Common is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Goathurst Common in your area for new build mastic?
Yes, Goathurst Common is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is the work guaranteed?
Yes. Every job comes with a 12-month guarantee.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix does not last, we can help.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What new build mastic looks like in Goathurst Common
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
